Scansion (/ˈskæn.ʃən/ SKAN-shən, rhymes with mansion; verb: to scan), or a system of scansion, is the method or practice of determining and (usually) graphically representing the metrical pattern of a line of verse.[1][2] In classical poetry, these patterns are quantitative based on the different lengths of each syllable,[3] while in English poetry, they are based on the different levels of stress placed on each syllable. In both cases, the meter often has a regular foot. Over the years, many systems have been established to mark the scansion of a poem.[4][5]
